9 Claims. (Cl. 33197) The present invention relates to a hinge butt locating gauge and more particularly to a template for locating complemental hinge butt recesses in doors and door frames.

Gauges or templates have been made and used heretofore for locating hinge butt recesses on doors and jambs so they may be routed out. In each instance the template had to be reversed, moved from one location to another on door or jamb, or separate rules or other measuring devices used to assist in locating the template.

One of the objects of this invention is to provide a template that may be set up for standard door heights and hinges without the use of a rule or other measuring device.

' is of suflicient thickness to receive the jamb and nail pins' Another object is to provide a template that will locate complemental hinge butt recesses on door and jamb with the same end up and without adjustment, change or shifting of any part.

A further object is to provide a template that will locate complemental hinge butt recesses on door and jamb where either two or three hinges are required without change or shift in the template.

Further objects will be apparent from the detailed description which follows with reference to the drawings, in which Fig. 1 is a plan view of the complete template located on a door;

Fig. 2 is an enlarged view of the upper frame member of Fig. 1 with a portion of a side member broken away; Fig. 3 is a side view of the frame member of Fig. 2;

Fig. 4 is a view on line 4-4 of Fig. 2;

Fig. 5 is a plan view of the frame member of Fig. 2 showing the location of the template on a jamb;

Fig. 6 is an enlarged view of one of the spacing members between frames;

Fig. 7 is an enlarged sectional view taken on line 7-7 of Fig. 5; and

.Fig. 8 is a view similar to Fig. 7 but showing the position on a differently sized jamb.

In accomplishing the objects of this invention a template is provided for the standard door sizes of today which are universally 6 8" and 7 in height. Other heights are considered custom sizes and the present template may beruled for them if so desired. In the present modification three aligned frame members are used, each having router openings that are adjustable in size for the size of hinge to be used. The center frame member carries indicia means for locating frame spacing members according to the height of the door while the end or outer frame members have indicia means for locating their respective frames on the spacing members for the hinge butt size to locate the top hinge butt 7" from the top of the door and the bottom hinge'butt 11" from the bottom of the door when the top stop member is properly adjusted; When the height of the door and size of hinge butt is known the recesses are automatically fixed for todays standards.

With reference to the drawings, Fig. 1 shows one form 2,869,245 Patented Jan. 20, 1959 of the invention in place on a door 8. It includes three spaced frame members 10 held together by spacing members 12 and a top stop member 14. Each frame member has similar adjustable router openings, jamb pins and nailing pins, and will be broadly described with reference to Figs. 2-4. Frame 10 of Fig. 2 may consist of an elongated narrow side member 16 and a wider guide side member 18 spaced apart by channeled shaped end plate members 20 leaving the central portion open for router opening 22.

The side members have two series of oppositely disposed staggered guide pin openings 24 to receive hinge guide pins 26. The upper row of openings 24 are for 3", 4" or 5" hinge sizes while the lower row is for /2" variations in hinge sizes. As shown in Fig. 3, if the hinge size is.3", guide pins 26 will be inserted in hole 24 above the 3 in each series. The two guide pins 26 and side members will guide and limit a router for a 3 hinge butt recess. For a 5 /2" hinge, the pins would be inserted in the extreme bottom holes 24 of each series. An end member 28 is affixed to each end plate member 20 and to be described, to receive the spacing members, and to be held thereon rigidly without wobbling or turning.

The wider side member 18 extends below end plate member 20 and the narrow side member 16 to form a guide strip 19 that is laid alongside one edge of a door and has an inwardly turned upper lip 21 to space the hinge butt recess from that edge of the door.

End members 28 are apertured as at 30 (Fig. 4) to receive either spacing members 12 between frames or stop member 14 on either of the end frames.

To assemble the template as thus far described, it will be noted in Fig. 1 that the center frame member end plates 20 have door height indicia on them with gauge lines for standard doors of 6 8 and 7. A spacing member 12 is inserted through aperture 30 in end member 28 until it just matches the proper gauge line and is locked in place by a thumb screw 32. Preferably each spacing member 12 is dimpled as at 33 to receive thumb screw 32 in locking position for one size of door and as at 34 for the other, so the frame cannot twist or turn when properly locked. The two end frame members 20 are the upper end of the door. 'to be positioned on the edge-of a door.

now located through their apertures 30 over the spacinglast named frame members and similar thumb screws 32 located in their respective end members are tightened on the spacing members. Dimples 36 may be provided in the spacing members 12 for the various sizes of hinges to again provide positive locking against slippage or twisting.

In positioning the frame members on the spacing members 12, each frame member must have its wider guide side member in alignment so that the guide strips 19 may be aligned along one side of a door 8 (Fig. 1). The outer end plate members 21) of the two outer frame members 10 are marked for right hand or left hand doors as at 37 and 38 respectively. To determine whether the door to be hung is right or left handed, the worker faces the side of the door on which the hinge pins will be visi-. ble after the door is hung. If the hinges are on the workers left it is a left hand door, and if on his right it is a right hand door. Stop rod 14 is then inserted through an aperture 30 at the properly designated end of the template until it rests against or is associated with the nearest guide pin 26 and is of such a length that it will assure the worker that the upper edge of the top hinge will. be substantially 7" from the top of the door. This will space all frame members a predetermined distance from The template is now: ready Rod'14'has a flange or lip 40-that is adapted to fit over the upperedge of adoor. near the location of the upper hinge. The template, consisting of the three frame members 10, is laid along the edge of the door to be routed with guide strips 19 aligned and abutting the edge of the door that will be adjacent the door frame stop so that lip 21 will overlie that edge and prevent that portion from being routed.

Each end member 28 and its end plate member 20 of each frame member 10 is apertured as at 41 to slidably receive nailing pins 42 therein (Fig. 4). Preferably nailing pins 42 may have limiting members 44 thereon, spaced from the head of the pin, that contact end members 28 on being nailed to limit the depth that the head may be driven so they may easily be removed. Pins 42 may also have stop collar means 46 positioned on them so that they cannot fall out of apertures 41. properly positioned on the door edge, nailing pins 42 are driven into door 8 to temporarily hold the template in placefor routing. The router is then rested on the side members 18 and guide pins 26 of one of the frame members, adjusted for required depth of cut, and the proper hinge butt recess routed out between the side membersand guide pins 26.

If only two hinges are to be used, only the two outer frame members 10 are routed out while the center frame member is unused. With stop member 14 resting on its nearest guide pin 26, the indicia 35 on the end plate memher is so placed that the outer frame members are positioned for the proper hinge size relative to the size of door fixed by the center frame member.

Without. further adjustment or reversal, the template may be used for mortising the door jamb. Each frame member 10 has apertures 50 in series alignment when the template is properly assembled and a similar series of. alignment of apertures 52 in the end members 28 and plate members 20 from one end of the template to the other. In each of these apertures 50 and 52 a jamb pin 54 isslidably mounted. To prevent the pins 54 from dropping out of apertures 5052, they may have stop shoulders 56 formed thereon to cooperate with. a shoulder portion 57 of apertures 50-52. The upper ends of apertures 50-52 may be capped in any suitable manner as by caps 58 and a'spring 59 is interposed between each cap 58 and the inner end of each jamb pin 54 to yieldingly press the jamb pin outwardly from its aperture (Figs. 4, 8). The row of jamb pins 54 in their apertures 50 onthe aligned frames form a series of stop members for 1%" doors while the other row of pins (farthest from the edge of the jamb) form a series of jamb guide members for 1%," doors.

As shown in Figs. 5, 7 and 8, the template assembly is placed against the side of the jamb 60 to be mortised with. stop rod 14 flush against the head jamb (Fig. If the door to be hung is 1% thick the row of aperture 50 jamb pins are aligned against the face of jamb 60. If the door is 1 thick the row of aperture 50 pins are pressed inwardly into the frame members against the jamb 60 (Fig. 8) and the row of aperture 52 pins are aligned against the face of the jamb to guide the template into proper position and nailing pins 42 are nailed in to support the template in position. Because of the series arrangement of jamb pins they are alignable from frame member to frame member to guide the template or gauge to'its proper position on the jamb. Preferably lip 40 of stop member 14 is about A thick so that hinge butt recesses mortised in the door jamb will give the door that amount of clearance when the door is hung.

When mortising rabbeted exterior door frames or if door stops are already in place, narrow side members 16 of the frames 10 should be abutted flush against the rabbctted edge or stop. The thickness of. the narrow side member (preferably ,6 will give the proper clearance forthe door at this point.

When the'template is Other modifications. of the invention will be apparent to those skilled in the art and may be made without departing from the scope and spirit of the appended claims.
